DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift cargo handling apparatus excellent in handling long-sized loads.

[0002]

2. Description of the Related Art Generally, a forklift is provided with a pair of left and right forks, and this fork is inserted into a frontage of a pallet to mainly carry pallets.
As shown in (1), the load g may be placed directly on the forks f, f and transported.

[0003] In particular, when the load to be conveyed is, for example, a bundle of long log members h, the fork f, the fork width W of f, the lifting tool c for raising and lowering the mast b.
The stability of the load g in the left-right direction is maximized along the finger bar d, and the forks f, f are tilted rearward to maintain the stability in the front-rear direction.

[0004]

However, according to the above-mentioned prior art, when the length L of the load g is larger than the fork width W (for example, L / W is twice or more), Is
The stability of the load g during transportation is poor, and there is a danger that the load g may fall from above the fork f.

The present invention has been devised in view of the above-mentioned problems, and is based on the provision of a link-shaped load holder having a plurality of arms protruding outward from the fork body in the vehicle width direction. It is an object of the present invention to provide a forklift cargo handling device that can solve the above problem.

[0006]

SUMMARY OF THE INVENTION The present invention provides a forklift which is provided on a lifting device for raising and lowering a mast of a forklift and extends forward of a vehicle body. One end of the fork base is pivotally supported and extends along the fork base. A load handling device for a forklift, comprising a link-shaped load holder having a plurality of arms protruding outward in a vehicle width direction.

[0007]

By projecting the link-shaped load holder outwardly in the vehicle width direction from the fork base, the width of the load holding the load together with the fork base is increased, and the load can be stably supported.

Further, the fork base is constituted by a fork of a forklift and a sheath which is detachably mounted on the fork, and a load holding device is provided on the sheath to provide a long load. It is easy to handle and can be loaded and unloaded with a regular fork.

Further, by fixing the load holder in a state along the fork base and in a state protruding outward,
This is preferable because the load holder can hold the load without inadvertently changing its position due to vibration, centrifugal force, or the like generated while the forklift is running.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. The cargo handling device 1 of the present invention includes a fork base 2 which is arranged on a lifting / lowering device for raising / lowering a mast of a forklift and extends forward of the vehicle body, and a load holding device 3 which can protrude outward from the fork substrate 2 in the vehicle width direction. .

In the present embodiment, the fork base 2 includes, for example, a fork 6 engaged with, for example, a finger bar of a lift bracket for raising and lowering a mast of a forklift, and a fork 6.
And a long sheath 7 formed with a hollow portion 7A which can be detachably attached to the outside, and both are integrally fixed by screwing a bolt B through a hole 7B formed in the sheath 7. Is done.

In this embodiment, the load holder 3 includes two slidable arms 4A and 4B pivotally supported by brackets 10 and 11 fixed to the side wall of the sheath 7, and the arms 4A and 4B.
A substantially parallel link mechanism comprising a link body 5 which is connected to the link 4B and rotatably supported by pins P1 and P2, and swings the arms 4A and 4B, thereby connecting the link body 5 to the fork base 2 From the vehicle width direction outward,
The width of the load supported by the arms 4A and 4B and the link body 5 is increased.

In the present embodiment, the arms 4A and 4B are fixed at a position along the fork base 3 (indicated by a solid line in FIG. 1) and in an outwardly protruding state (indicated by a dashed line). Equipped.

In this embodiment, the fixing means 9 is provided with the arm 4A.
In addition, a projecting portion 12 extending beyond the pin P1 and a first locking hole H1 are formed in the projecting portion 12, and the link body 5 is brought close to the fork base 2 in the link body 5. Protruding piece 13 substantially overlapping with the overhang portion 12 at the
Is provided with a second locking hole H2 communicating with the first locking hole H1, and the arms 4A and 4B are moved from this position by approximately 90 °.
A third connecting the first locking hole H1 in the swinging state
And the first, second, and third locking holes H
1, H2, and H3.

Therefore, in order to fix the arms 4A, 4B and the link body 5 along the fork base 2, the fixing pins 1
4 is inserted into the first and second locking holes H1 and H2, while the arms 4A and 4B and the link body 5 are fixed in a state of protruding outward, the fixing pin 14 is fixed to the first and third holes. Lock hole H
1. Insert into H3.

As described above, by providing the fixing means 9 for fixing the load holder 3 at one of the positions, the load holder 3 changes its position due to vibration, centrifugal force or the like during traveling of the forklift. Can help prevent the load from falling.

In this embodiment, the height K1 of the sheath 7 is
Is smaller than the height of the insertion port of the wooden flat pallet, and the thickness K2 of the load holder 3 is smaller than the height K1, and is located within the height K1. The load holder 3 is configured to be inserted into a normal wooden flat pallet along the fork base 2. In such a case, the load holder 3 simply functions as a so-called sheath fork that increases the fork length.

FIG. 2 shows another embodiment. As shown in the figure, the load holders 3 are provided on both left and right side walls of the fork base 3, and according to such a configuration, two long loads g1,
g2 is preferable in that it is possible to juxtapose and carry cargo.

FIG. 3 shows another embodiment of the fixing means. In this example, an arc-shaped projecting piece 15 centered on the pin P1 is formed in the link body 5, and in this example, five locking holes H4 are provided at an equal angular pitch around the pin P1. Are illustrated. Such a configuration is preferable in that the load holder 3 can be adjusted to a width suitable for the long dimension of the load, and the width of the passage required for traveling can be minimized.

As described in detail above, the cargo handling device of a forklift of the present invention can be modified into various modes such as mounting the load holder directly on the fork of the forklift and improving the strength by providing three or more arms. sell.

[0021]

As described above, the cargo handling device of a forklift according to the present invention is excellent in handling loads of long objects, and also enables handling of loads by ordinary forks. In addition, the position of the load holder is fixed so that workability can be improved and safe work can be performed.
